Explorer neutral tow won't work

[fastcat]

Like so many others on the forum I decided to make my own "neutral tow kit" for my 2002 Explorer 4X4. Bought the LED from Radio Shack and wired it into the truck.

Today I took the truck to our local dealer and asked them to flash the computer to enable the neutral tow.

No problem, we do lots of these.

So a few hours later they call and tell me the computer has been re-programmed but the neutral tow won't engage.

The LED is on dim whenever the key is on. When the key is off it flashes dim about once every two seconds and never stops.

When the key is on the LED is on dim all the time.

When I first turn the key on the LED will get bright for about two seconds then go the the dim mode and stays there.

The bulb check never happens and the transfer case does not go into neutral.

Any "Gurus" here that recognize the symptoms?

I cannot directly suggest how to solve your problem.

I can however tell you how mine works.
I have a 2004 Explorer 4X4 with the FORD NTK.
Th NTK was installed at the dealer and the programming done at the same time about three years ago.
The light is NOT on (even dim) when the Explorer is in normal mode.
When you go through the required sequence the light flashes untill you do the sequence then it stays on full time BRIGHTLY.

When the transfer case disengages I can hear a slight click as I am going through the sequence and push the 4&4 dash button.

I have had no issues at all and have used it many many times, including our four month trip to Alaska this year.

good luck -- Dale

Thanks Dale!

That's how I thought it should work but the dealer was no help.

I have a few friends that either currently work at or are retired from Ford dealerships. I guess the next step is to ask them for help.

Now if I could just find out what the constant flashing light means.
